Good ideas thanks.
If I used, for example, a 1000W High Power Dc 48V 20.8A supply and a 320kv outrunner am I correct in assuming that would increase rpm. I could buy a 200kv motor and still use 1000W High Power Dc 48V 20.8A supply na dget benefits. I suppose somewhere down the line there is a torque trade-off but thats set aside at the moment.
